CHARLES RIPPIN, on ST. LOUIS, MISSOURI- MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 526,541, dated September 25, 1894. Application filed August 5; 1893. Serial No. 1 N mode To all whom it may concern-.-

Be it known that I, CHARLES RIPPIN, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improvement in mixing machines and consists in the novel arrangement, combination and construction of parts as will be more fully hereinafter described and designated in the claims.

In the drawings: Figure 1 is a perspective View showing my invention ready for operation, parts being broken away to more clearly show the same. Fig. 2 is a longitudinal section taken on the line 22 of Fig. 3. Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2. Fig. 4. is an enlarged detail section of one of the sections which are used in carrying out my invention;

1 indicates an outer casing which is constructed in two portions 2 and 3, each portion being provided with marginal flanges 4 and 5 for the purpose of allowing said portions to be bolted or riveted together. This casing is mounted on a supporting frame 6, the upper endof which is connected to the marginal flanges in any desirable way.

Mounted on the upper portion 2 of the easing 1 and opening through said casing and located in the position shown in Fig. 1 is a hopper 7.

Connected to the lower portion 301: the casing 1 and opening through said casing is a tail-chute 8. (See Fig. 1 for illustration.)

Mounted in the casing 1 and held in position by bearings 9 and 10 are two parallel shafts 11 and 12. Mounted upon one end of the shafts 11 and 12 are two gear wheels 13 and let which mesh together so that said shafts will rotate in opposite directions. Mounted on the shafts 11 and 12 intermediate of their bearings are two conveyers 15 and These conveyers are constructed in sechub 18 and formed in each end of said hub, is an annular recess 19. Mounted on the shafts intermediate the adjacent hubs l8 and constructed to conform with the annular recess thereof is a compressible washer 2O whichis made of rubber or any other suitable material. The sides of the sections 17 are provided with a series of sections 19 each having parallel corrugations 2O as can be which are desired to be mixed and spread the same over the entire surface of the section as the same revolves.

2O indicates lugs formed on or fixed to the sections 17. Said lugs are so arranged on the sections 17 that the lugs on one section of the conveyer 16 will not come in contact with the lugs formed on sections of the conveyer 15. The object of these lugs is to more fully facilitate the mixing of the contents, and also to increase the frictional surface that is brought to bear on the contents. Said lugs should be of such a size as not to interfere with the adjustment of the sections 17. These The shafts 11 and 12 are screw threaded intermediate their bearings and provided with 1 nuts 21 and lock nuts 22. These nuts are to engage the outer section and by screwing these nuts on the said shaft it will compress the washers 20thus bringing the sections 17 closer together, which will be required for mixing fine material. Mounted on the shaft 12 at the opposite end of the gear-wheel 13 is a belt pulley 23 which is adapted to receive a driving-belt from any suitable power.

The lower portion 3 of the section 1 is constructed to conform with the outer periphery of the sections 17 and will give said sections a greater mixing surface than as thoughit was fiat.
